Title: Automated system for modeling faulted multi-valued horizons
Inventor: VASSILEV APOSTOL TODOROV
IPC: G01V11/00
Filed: 2002-06-05
Granted: 2007-08-21
Abstract: In a method for modeling a reservoir having a horizon surface with a reverse fault, a volume of the reservoir is partitioned into fault blocks. A boundin g surface of each of the fault blocks includes a portion of the reverse fault. The interior of each of the fault blocks includes only single valued horizon surfaces. Horizon data describing the reservoir is partitioned into patches, each patch corresponding to a fault block. A horizon surface patch model is derived from the data patch in the interior of each fault block. The horizon patch model includes an up-thrown or down-thrown fault trace, which defines the intersection of the surface patch with the bounding reverse fault. Continuity constraints are defined to ensure that horizon surface patch mode ls on the opposite sides of the reverse fault coincide outside of the real faul t.

Patent CA-2461995-C (CA)
Inventor: CHEN SONGHUA
IPC: G01V3/32
Filed: 2002-08-16
Granted: 2010-11-23
Abstract: Many reservoirs of interest include heavy oil. In such reservoirs, parti at normal temperatures, many instruments commonly used for formation evaluation may not be able to distinguish between heavy oil and bound water in the formation. Passive or active heating is used to elevate the temperature of the fluids in the formation. At elevated temperatures, distinguishing between heavy oil and bound water is easier. Of particular interest is the increase in the resolvability of the transverse relaxation time T2 of NMR spin echo measurements. Additionally, the dielectric constant and the loss tangents of water and heavy oil show different temperature and frequency dependence.

Filed: 2004-04-14
Granted: 2011-12-20
Abstract: A controlled torque drive for a motor of a barrier operator including a current sensor coupled to a current conducting path that is in series with the motor. The current sensor is configured to sense the current level in the current conducting path and provide a signal indicative of the current level in the current conducting path to a current controller that restricts the current level to the motor when an obstruction is encountered by the i movable barrier. The current controller continues to restrict current to the motor for a period of time while the motor attempts to move the movable barrier through an obstruction. In variations, the current to the motor is limited by an analog current controller, and in other variations, current is limited by a digital current controller.

Title: Method for controlling solute loading of polymer microparticles
Inventor: BANERJEE SUKANTA
IPC: C08J3/215
Filed: 2004-01-21
Granted: 2010-08-03
Abstract: Solute-loaded polymer microparticles are obtained by immersing microparticles in a bath comprising a selected solute dissolved in a ternary solvent system. A first solvent of the ternary system is a strong solvent for both the solute and the polymer from which the microparticle was formed. A second solvent is a weak solvent or non-~ solvent for the solute and the polymer (tuning solvent). A third solvent is a weak solvent or non-solvent for the solute and polymer, but serves as a co-solvent with respect to the first and second solvents in that it is miscible with both the first and second solvents. The amount of solute incorporated into the microparticles is controlled by adjusting the ratio of solute with respect to the microparticle polymer, and by adjusting the composition of the ternary solvent system, principally the amount of tuning solvent. The method is particularly useful for providing libraries of combinatorially encoded microparticles containing distinguishable dye loadings, particularly distinguishable fluorescent dye loadings.
